The phylogeography of the Japanese pond turtle, Mauremys japonica (Temminck and Schlegel, 1835), which is an endemic species in Japan, was studied by analyzing the variation in two mitochondrial DNA sequences, the cytochrome b gene and the control region. These analyses suggest that M. japonica comprises two major groups. The first one was found in the more eastern region, eastern Honshu Island and Shikoku Island, while the second was found in a western region, Kyushu Island and the Chugoku District (the westernmost part of Honshu Island). The boundary between the two groups is located in the Chugoku District. The nucleotide and haplotype diversities were very low, and these low diversities seem to have been caused by a bottleneck in the last glacial age. These results suggest that this species survived the last glacial period in two refugia, one in the central part of Honshu Island and the other one in Kyushu Island. Subsequently, population expansion took place in the postglacial period, and the groups from the two refugia extended their distribution ranges to the present boundary in the Chugoku District which represents a secondary contact zone.
